[Gameplay] fiora dashing through azir's ultimate

When playing I encountered a bug where fiora can dash through azir's wall using her q. all dashes are supposed to be cancelled (ex. Akali, gragas, graves) because they still hit the wall during their dash. Replication has come through multiple times setting up azir walls and having fiora q through it when azir is close enough. Im not sure if this is supposed to occur however if not then it is a bug and has happened multiple times.
